Rotating Fan Illusion
In the first case, the illusion stays for few seconds. But in the second case, it remains as long as the fan is rotating.

Stroboscopic effect. You will not see it in daylight. Tubelight, which has a high frequency flicker can cause this. Same effect is seen with car wheels or helicopter blades in films.mreccentric1}When you see a rotating fan, at the start it seems like rotating in opposite direction. Why does it look so? 2}This also happens when the fan is rotating at a very high speed.

Here is how it works. When the frequency of the light source matches the RPM of the fan it appears stationary.Anku2993dear please explain some more about this effect.
